of  the  original  copy  and  in  keeping  with  the 
filming  contract  specifications. 


Original  copies  In  printed  paper  covers  are  filmed

whichever  applies. 

IVIaps,  plates,  charts,  etc..  may  be  filmed  at 
different  reduction  ratios.  Those  too  large  to  be 
entirely  included  in  one  exposure  are  filmed 
beginning  in  the  upper  left  hand  corner,  left  to 
right  and  top  to  bottom,  as  many  frames  as 
required.  The  following  diagrams  illustrate  the 
method:

The  anterior  ])ortion  of  the  liody  is  called  tin'  lirod :  it  varies 
frreatly  in  form,  and  is  Joined  hy  memlirane  to  the  protliorax. 
Usually  (lie  hirid  i)ortion  is  Ijiil  slifjlitly  narrowed,  and  enters  the 
iintei'ior  part  nf  tin,'  protliorax;  sometimes  the  pari  l)(diin(l  the- 
eyes  is  suddenly  narrowed  iiiid  eonstricteil,  fdrminj;'  ;i  neck.  .>r 
firadiially  narrowed  and  iiinch  prolmiji'ed,  arlienlaliiiu'  with  t.ie 
protliorax  hy  a  semiulolmliir  condyle,  as  in  sonic  ('arai)idie  and 
tiie  JJrenthidie. 

The  siirfaei'  of  the  head  consists  of  a  solid  horny  plate;  above, 
it  is  frccpieiitly  marked  by  a  siniile  suture,  rnnniim'  transversclv 
between  or  ill  front  of  the  antenna'  ;  this  is  callcij  (he  </i//ii'(il  cir 
/'roiildl  .111/ lire.  The  portion  in  front  of  this  siitnre,  when  dihitcd 
so  as  to  jiroject  over  the  moutli,  as  in  many  Scaraba'idie,  is  called 
the  rli//i)'iiti:  when  small  it  is  named  I'/iislmtKi.  and  is  sometimes 
iiieinbranoiis  or  coriaceous,  instead  of  horny  like  llic  rest  cf  the 
surface.  'I'lie  anterior  pnrlion  of  tnc  head  is  sonicl  imc.s  prolonu'i'd. 
so  that  tho  distance  belwecn  the  eyes  and  iiiniiih  parts  is  greater 
in  len;.i'th  than  the  rest  of  the  head;  when  thus  fnrnicd  the  head 
is  called  roMralr.  and  the  proloiiired  portion  the  ros/rnrii  or  In'ii/r. 
The  /■o,>'/;v/ HI  varies  frreatly  in  form  and  Iciiii'lh;  it  is  often  mil 
narrower  than  the  head  and  oven  shorter,  rarely,  as  in  IJalaiiinus, 
very  slemler,  alnmst  lilifonn,  and  as  lon;a'  as  the  entire  body.  The 
presence  of  the  rostrum  is  (piite  fi^tuieral  in  the  sub-order  Mhvii- 
chophora,  l)ut  not  cliaraetcristi(;  of  it,  as  the  rostrniii  is  dltcu 
absent  her(!  unci  present  in  other  isolated  genera  of  the  Coleijfi- 
terous  series.

4.  LaincHiilc:  In  lliis  l}i)0  tiio  outer  joints  are  prolonged  ante- 
riorly, opposing  Hat  suri'act's  to  eaeli  otlier,  wliidi  may  •<(•  hronglit 
closely  in  I'lmlaci,  I'orniing  thus  a  transverse,  or  rarely  i(jun(le(i, 
elub,  Kiippoiled  at  one  side  liy  llie  stem  of  liie  antenna,'.  Tliis 
lorm  obtains  in  all  Searabiuidie. 

Oilier  modiliealions  have  hi'en  named,  but,  with  the  e.\eeption 
of  two,  tliese  liave  not  been  used  in  the  present  treatise.  Tiiey 
are,  the  irri'ijuldr  and  ((ijiilluri/.  The  lirsl  name  is  ajiplied  to 
those  antennie  in  which  ceruiin  of  the  joints  have  an  iinnsmd  (jr 
extraordinary  dcveloi)ment,  as  in  t!ie  (/yrinidie  or  I'latyp.syllidie; 
when,  liowever,  the  irregularity  is  sexinil,  as  in  the  males  of  some 
Meloe,  the  antenna'  are  said  to  lie  (Itjor-iiirtl  in  that  se.\.  The 
capillari/  form  is  a  modification  of  the  clavale  type,  in  which  the 
joints  are  long,  slemler,  and  hair-like,  and  very  luosely  artieulated, 
as  in  many  Triehopterygidie,  some  Scaphidiidiu,  and  in  l)asyeerus. 
in  this  i'orm  the  joints  are  fretpiently  surrounded  at  tip  with  a 
circle  of  longer  hairs,  in  wliith  ca.-n;  the  aiiti'iiiia'  are  said  to  be 
ri'riirclldlc. 

Aiiteiiiiie  are  called  (ji'iHi-ntiiti'  when  thi'  second  joint  is  ufli.xed 
so  as  to  malic  an  angle  wiili  the  first;  the  following  joints  eoii- 
timiing  in  the  line  of  the  second.  In  this  form  the  lirst  or  basal 
joint  is  usually  niueli  longer,  and  is  called  the  .<c<ipr.  \N'lieii  the 
geniculate  form  is  at  the  same  time  capitate,  the  joints  interme- 
diate iietween  tiie  scape  and  club  are  ealle(i  tho  J'lniiclt;.  Tliesi' 
terms  are  used  more  especially  in  the  Khyiiehopliorous  series,  in 
which  the  gcniculatc-i'hivate  type  is  the  most  common  form  of 
antenna'. 

Moirii. — The  month  of  Coleoptera  is  mamiibnlate;  that  is  to 
sav,  it  }!('  scs.~es  two  jiairs  of  lun'izonlally  moving  |iieces  for  the 
jiiirposc  (if  seizing  the  food.  Aliove  the  inoiith  there  is  usually 
a  small  piece,  iiioi'e  <ir  less  transverse,  articulating  with  the  epi- 
stonia,  which  is  called  the  iijiper  lip  or  liilirniii. 

The  Idliriiiii  is  variable  in  foriu,  and  in  nearly  all  the  families 
of  normal  Coleoptera  is  distinctly  visible.  It  may,  iiovvever,  be 
I'oiiipleti'ly  united  with  the  epistoma,  lU'  retracted  beneath  it,  and 
thus  entirely  concealed.  In  the  rihyiichophiu'a,  excepting  Itliino- 
maeeridie,  riatypodiiue,  ami  .\nlhribidu',  the  labriim  is  entirely 
wanliiitf.

The  serrate  clawH  of  J'JIajihropiis  Motseh.,  an  Asiatic  jreiius, 
is  a  Very  singular  character  to  occur  in  the  prest'ut  Iriiie.  The 
species  of  this  <renus  resemble  Tucln/s  and  notably  iiK'iirrtis.  etc. 

The  geiu'ra  known  to  (n'ciir  in  our  fauna  are  as  follows : —

'I'lie  males  have  the  anterior  tarsi  with  three  joints  feebly 
dilated  and  s(piamuiose  lienealh. 

Piviijiiita  seems  also  better  ])laced  here  than  elscwln're,  and 
appears  to  lead  towards  the  'rrechini  in  tiie  same  nnmner  that 
OlislhapHs  does  to  the  Lebiini. 

A  study  of  tiie  form  of  the  lignla  and  paraglossa;  of  those 
gcnira  which  are  acknowledged  on  all  sides  to  be  undoubtetl 
mendicrs  of  the  presiint  tribe  J'ldli/iiiis,  Valal/nis,  and  OliMho- 
jiiiK.  seems  to  .show  wiiat  little  value  these  organs  have  in  the 
deliiiitiou  of  tribes  and  gi'oups  of  genera.  The  ligula  of  Olis- 
Iho/ms  is  very  plainly  that  of  many  Lebiidcs,  /'Idti/iiim  reproduces 
Very  closely  that  of  J'liu-oxlichux,  Cdlallnix  proper  is  as  nearly  as 
pos^iliie  intermediate  betwi'cn  the  two,  while  the  section  I'nxln- 
darltjla  is  a  inodilication  of  I'hih/inis.  The  tip  of  the  ligida  is 
frceii  I'lalijnux  and  l'risfii(l(i(li/lii,i\u{\  not  free  in  theothergencra. 

Tnc  menium  tooth  also  seems  to  furnish  characters  of  an 
evrjiescent  nature.  In  some  /'/(//_)//(?/«,  especially  those  in  which 
the  hind  angles  of  the  thorax  arc  distinct  {hnaiitromartiiiiahis, 
ovi/Ktinit^,  etc  ),  the  tooth  is  longitudinally  impi'cssed  and  emar- 
ginate  at  tip,  while  in  the  A'joninn  type  the  tooth  is  very  obtuse. 
The  sam(!  variation  is  observ(Ml  in  (Uthilhux,  some  having  (juitc 
an  acute  tooth,  others  even  bilid.

Group  I. — Flatyni. 

Tliis  group  might  easily  Ik-  .sopiiratod   in  many  minor  sut)- 
(livisioiis  by  including  Uio  genera  not  rupresentud  in  our  fauna. 
Tiio  I'ollowing  gcnuni  occur  with  us: —

Olis/fid/iiix  is  rei)r<'s('iiti'd  in  tlio  Atlantic  region  hy  two  species; 
the  olIiiT  genera  occur  on  liotli  sides  of  tin^  continent.  Of  I'n'n- 
loiii/cliiis  two  species  arc  known,  both  of  them  identical  witlt 
JMiropeiin  forms  (coiiiit/aiiiifiis  and  frrrirola),  and  \mvr,  probal)ly 
been  introduced,  (lie  first  ineulioued  being  ratiier  widely  spread 
by  coniiuerce  over  the  globe. 

<iroup  11. — Perigonse. 

This  group  is  represented  by  one  genus  Perhpnn,  which  has 
for  its  synonyms  Trcciiiciis,  Nestra,  and  8paliiiinis.  The  meninin 
has  its  ejiilolies  prolonged  to  an  acute  spine,  the  ennirginalion  is 
deep  without  tooth.  'i'h(>  ligiila  is  narrow  and  truncati!  ut  tip, 
tlie  je.iiaghissfc  sh'nd<'r  and  a  lillle  longer  than  tin;  ligula,  and 
uniteil  with  the  latter  by  a  thin  almost  transparent  mi'nd)rane, 
which  e.Meiids  fruiii  the  l)ase  of  the  paraglossu!  to  the  tip  of  tlic 
iignla. 

The  nnteiniir  are  rather  stout  beyond  tiie  tliird  Joint,  and  the 
sectnid  is  as  long  as  tin'  lliird. 

Tlicrc  is  certainly  no  reason  why  Pcrirjovn.  shotdd  l)e  placed  as 
a  TrniK'atipenne.  The  two  supra-orbital  setie  remove  it  from 
association  with  the  llarpalide  series.  Taking  its  inlire  organi- 
zation, it  seenis  better  placed  in  the  prosont  tribe  than  anywhere 
else.

From  the  p-reat  -inmber  of  j.?enera  which  have  been  established

Characters  drawn  from  the  ligida  and  |tai'aji|ossie  have  here,  as 
in  tin-  Lebiini,  been  pushed  to  nn  extreme,  and  the  study  of  them 
from  dissections  proves  that  in  both  tribes  they  have  not  the  great 
value  which  has  been  assigned  to  them. 

The  tribi!  llarpalini  may  bo  divided  jirimarily  b\^  the  tarsal

In  a  review  of  onr  species  of  the  genns,  published  by  Dr.  Horn

full  discussion  of  the  characters  wliiuli  serve  to  divide  the  speeies 
ill  siiltgeiierii  uiid  lower  groups — the  trilid  anterior  tibial  spur, 
the  spur  ijrouder  ut  middle  and  the  slender  spur.  In  two  .species, 
lid r pall liileti  and  ojiocuIuk,  tlie  first  joint  of  the  anterior  tarsus  of 
the  female  is  dilated,  and  in  the  former  that  joint  is  soniewliat 
l>rok)ngeil  under  the  second. 

Xkstu.notus. — Anterior  tarsi  hroadly  dilated  in  the  male,  the 
first  four  joints  d"nsely  sponuy  puheseeiit  heneath,  niiddh'  tarsi 
with  four  joints  less  widely  dilated  and  sixnigy  piilieseeiit  Iieiieath, 
the  lirst  entirely  glabrous,  ]tosterior  tarsi  slender  and  long.  Klytra 
with  one  dorsal  piineturo.  The  liguhi  is  rather  narrow  and 
parallel,  the  paraglossse  broad  and  a  little  longer  than  it. 

Comparing  the  dilferenees  between  the  liguhi  and  parnglossa' 
with  those  (tbserved  in  Har/iahis  there  does  not  seem  any  viiiid 
reason  for  retaining  the  genus  ajiart  from  Anisoildcli/lus,  and  the 
speeies  will  find  a  suitable  position  between  the  oitKiroidn/i  and 
.svvvV'CM.s-  groups  of  that  genus. 

Ami'IIasia. — Here  the'  eharaeters  are  essentially  those  of  vhu.s'o- 
(hnii/his  .ii'ricciis.  The  paraglossa)  are  similar  in  form  to  Aniso- 
daetylus,  and  merely  a  little  longer. 

l']iiiV'riuoin's — The  se.xual  eharaeters  and  those  derived  from 
the  posterior  tarsi  are  jireeisely  those  of  Jiiisoilinti/liis  <miiif! 
and  l/i/iift.  The  paraglossiu  are  a  little  broader  than  in  typical 
A>iisii<l(ifti/li. 

Si'oNddi'i  s. — TIk!  liguhi  and  paraglossic  are  intermediate  in 
strueliire  between  the  typical  Anisitiluctijlu.t  and  Xi'slonohis,  and 
the  liguhi  is  free  for  a  greater  distance  at  tiji.  Tlie  sexual  eiia- 
ra(!ters  are  those  of  tlie  amnraidcs  group.  The  iiosteiior  tarsi 
lue  how(!ver  slender.  The  elytra  being  i)iiiietiilate  and  wilii  a 
single  dorsal  puncture,  this  species  forms  an  intermediate  liel-veen 
the  ilisraiili'us  group  and  sericrK)'. 

From  the  alxive  remarks  it  would  ap|)ear  that  these  genera  are 
inseparablo  from  AniKodacli/lun. 

It  is  worthy  of  note  that  we  may  have  in  A)ii.-<o<hi'ti/lufi  more 
than  one  setiii-erous  piineture  at  each  angle  of  the  cly])eus,  while 
in  most  Carabidiu  there  is  liut  one,  and  even  this  may  be  lost.

Sub-Family  I  — NOSODENDRIN.E. 

Hut  a  single  genus,  Xesodondron,  constitutes  this  sub-family. 
It  is  reproseuteil  in  Europe  by  one  spi'cies,  and  In  the  Atlantic 
and  Pacific  regions,  respectively,  also  by  single  species.  It  Is 
siilficlently  (llstlngulslied  liy  the  large,  elongate,  scml-elllptical 
nicnluni,  entirely  closing  the  mouth  below,  leaving  only  a  very 
narrow  portion  of  (he  maxilla;  to  fill  liie  fissurt;  on  cadi  side;  the

Sub-Family  H.— llVllUlIIXyE. 

In  this  sub-family  the  head  is  retracted;  the  mentum  small, 
(piadratc;  t!ie  liase  of  the  maxilla;  largely  exposed  ;  the  labrum 
distinct;  (he  antenna'  inserted  under  the  sides  of  the  head. 

We  would  arrange  these  genera  in  three  tribes: —

In  this  group  the  nntenniu  are  more  or  less  compressed,  some- 
times serrate;  the  last  joint  is  elongalo  and  roumied  a*  tip,  willi- 
oiit  appendages  or  siniiation ;  the  second  joint,  is  short,  sometimes 
very  short  an<l  transverse  {/.inidolti).  The  sexes  arc  similar  in 
appearance,  e.xce|it  in  one  sjiecies  of  I'IhiHiiuh,  where  the  elytra 
of  the  9  are  short  and  the  wings  wanting.  The  eyes  are  larger 
in  %  than  9,  but  arc  separated  liy  a  wide  .'^paee  both  above  and 
beneath  in  all  the  species.  In  the  S  the  last  ventral  segment  is 
small  and  narrow,  covered  i)y  the  scutate  last  oorsal,  which  varies 
in  form  according  to  genus  and  species.  Tlie  light  oi'gans,  when 
jne-ent,  are  more  developed  in  %,  than  9,  which  is  the  reverse  of 
what  obtains  in  the  group  Lampyres.  The  head  is  always  covered 
liy  I  he  hood-like  prothorax.  The  cpiplenrm  of  the  elytra  are  wide 
at  the  base;  the  inferior  (or  distal)  margin  is  reflexed,  and  eon- 
verges  more  or  less  to  the  lateral  margin  of  the  elytra.  The  elytra 
vary  in  color;  in  the  species  without  well-developed  light  organs 
they  are  lilaek,  with  the  single  exception  of  Pi/ropi/rfn  iixlirla, 
where  they  are  brown  iimrgincd  witii  testace(Uis,  as  in  the  brilli-

family.  It  is  prohahly  not  a  Lampyride,  but  where  it  may  he 
nuitai)ly  placed  we  do  not  know.

This  tribe  consists  of  liut  one  genus  represented  in  our  fanim 
by  a  moderate  numl)er  of  sjw'cies.  They  are  much  more  imiiicr- 
ous  in  tropical  America,  but  so  far  as  I  am  aware  do  not  (mciii 
in  other  countries.  Chauliognathus  diflers  from  all  others  in  dnr 
fauna  not  only  by  the  elongated  head,  and  singular  strurture  nl 
the  maxilhiry  lobe,  which  has  a  long  extensile  and  contractile 
fleshy  filament,  but  also  by  the  peculiar  arrangement  of  the  iiinicr 
surface  of  the  prothorax,  and  the  sexual  characters  oi  the  %. 

Trilx^  II.— TELEPnORINI. 

Excluding  0)nrlhi's,  ns  above  indicated,  we  have  no  improve- 
ment to  suggest  to  the  table  of  groups  already  given,  Classilica-

Group  I.— Podabrl. 

Although  tiie  species  of  this  group  differ  in  the  form  of  palpi, 
as  well  ns  in  the  tarsal  claws,  they  seem  to  indicate  but  one 
natural  genus.  They  are  more  numerous  in  the  northern  part 
of  the  continent,  and  gradually  fade  out  towards  the  tropics

The  gradually  thickened  middle  and  hind  tibia)  unfit  these 
insects  for  transporting  the  balls  of  material  which  serve  for  tiie 
food  of  the  larva^ ;  though  some  of  the  species  ilo  construct  linljs, 
they  bury  them  in  the  place  where  they  are  formed.  The  scmuiI 
difl'erences  are  frequently  strongly  marked,  the  male  having  horns 
on  the  head  or  thora.x.  The  epii)leuric  are  always  .larrow,  ami 
tiie  first  joint  of  the  tarsi  is  elongated.  The  anterior  tarsi  iue 
wauling  in  .some  species  of  I'lianteus,  and  the  claws  are  all  want-

The  following  groups  arc  represented  in  our  fauna: — 

Third  joint  of  lahial  p.nlpi  distinct; 

Anterior  coxne  very  transverse,  not  prominent.  Scatoxomi. 

Anterior  coxa'  short,  prominent ;  lahial  palpi  dilated.  ('(ii'ni.s. 

Third  joint  of  lahial  palpi  ohsolete.  O.NTnoi'iiAoi.

Our  only  representative  of  this  group  is  Chooridium,  containing 
two  moderately  small,  convex,  shining,  bronzed  black  sfjccics 
found  in  dung  They  resemble  Ilister,  with  finely  striate  clytrn. 
The  3-jointed  labial  palpi,  and  the  transverse,  not  prominent, 
anterior  coxaj,  readily  distinguish  it  from  the  other  groups.  The 
claws  arc  small,  without  onyehium,  but  the  tip  of  the  la.st  joint  <>(

Group  III. — Onthophagi. 

Several  species  of  Ontho[ihagus  from  the  Atlantic  .slope,  and

TiilM.  IX.— TRO(;i\l. 

Mandililus  and  hihnini  corni'ous,  prominent;  antenna!  9-  oi- 
10-joinled,  club  ;j-joiiited  ;  anterior  coxie  rounded,  subconiciil, 
prominent  ;  middle  co.xa;  nearly  round,  not  obli(pi(>,  I'ontijjuous ; 
epimera  of  the  metatliorax  covered;  epimera  of  the  iiiesotliorax 
widely  separated  from  the  coxa'  by  the  sternum;  ventral  segnients 
live,  not  connato  ;  abdomen  coveretl  by  the  elytra;  tarsi  with 
moderate  claws,  Iiul  no  oiiycliium. 

Tlu!  insects  of  this  trilie  are  oblonir,  conve.x  species,  liviiifj  in 
dried  ducomposiny;  sinimal  matter.    The  feet  are  scarcely  fossorinl

in  form;  llie  siirfuw  is  usually  rough,  and  covert'tl  with  a  crust 
of  (iirt,  reniovucl  with  great  ililliculty.  Our  «iif(;ic.s  are  iiuiiifrous, 
iiuil  belong  to  the  genus  Trox.  Tiiu  larger  speeies  iiuving  the 
sides  of  the  tiionix  not  eiliato  with  hairs,  were  placed  hy  Krieiison 
lis  a  separate  genus,  Oniorgus;  hut  the  characters,  as  observed 
l)y  Lacorduire,  are  indellnife,  and  it  i.s  not  retained. 

Tiie  genus  Trox  possesses  a  distinct  siridulatiiig  organ  ;  it  is 
an  elliptical  plate,  wilh  pearly  redeetions,  occupying  the  upper 
piirt  of  the  external  lace  of  the  ascending  imrtion  of  the  lirsl  ven- 
tral segment,  and  is  covered  by  the  elylra  ;  on  the  inner  surface 
of  the  fdytra,  near  the  nnirgiu,  about  opposite  the  inetatliorax,  is 
an  oval,  smooth,  jxilislied  space,  which  has  probably  some  con- 
nection with  the  slrididatiiig  organ. 


Sub-Family  II.— MHLOLONTIIIX/E. 

Tills  sub-family  holds  an  intermediate  jjosition  between  the 
Liiparosticti  and  I'leurosticti.  The  second  pair  of  alxloininal  spira- 
I'ies  is  placed  in  the  mendtrane  connecting  the  ventral  and  dorsal 
segiuents,  as  in  other  Hcaraba'ida;;  in  most  species  the  third,  and 
souietimes  the  fourth,  at  the  outer  limit  of  lliis  mend)rane;  tiie  lifih 
and  si.\lh  pairs  are  in  the  dorsal  portion  of  the  ventral  segments, 
liut  the  lines  connecting  them  do  not  divergi.'  strongly,  as  in  the 
I'leurosticti;  the  i.'venth  or  last  pair  is  usimllj'  visible  iiehind  the 
elytra,  but  variable  in  iiositioii ;  in  I'Mier  species,  forndng  the  first 
two  tribes,  however,  the  sidracles  are  placed  as  in  the  Laparosticti, 
all  being  in  the  connecting  iiiembiane. 

The  clypeus  is  usually  prolonged  and  margined  in  front,  so  that 
the  mouth  is  inferior,  but  in  (Jlaphvrini  the  mandibles  and  lal)ruiii 
are  prominent;  the  luandibles  are  corneous,  sliort,  pyramidal: 
the  meutum  large,  quadrate,  with  the  ligula  usuiiily  corneous  ami 
connate  with  the  inentum,  though  sometimes  free  and  membranous, 
as  in  the  Laparosticti;  the  clypeal  suture  is  usually  distinct,  trans- 
verse; the  antenmc  have  from  seven  to  ten  joints,  and  the  club  is 
always  lamellate,  sometimes  consisting  of  six  or  five,  hut  usually 
of  three  joints,  and  is  frecpiently  longer  in  tiie  males;  the  tarsi 
are  iihvays  perfect,  r)-jointed,  with  tiie  claws  variable  in  form,  and 
the  bisetose  onycliiuin  is  present  in  nil  the  trilics  except  Iloplini, 

The  s])ecies  feed  exclusively  on  living  ve!T(>t.,!)lo  niatter,  and  it 
will  be  seen  tliat  tlie  distinctions  between  it  and  tiie  otiier  suli-

'I'licy  nrc  ('Kiii<;nti'  hairy  insects,  usually  of  nictuUie  color,  found 
in  iargf  numbers  on  leaves  of  trees;   the  claws  are  clefi  al  tip. 

Suli-Trilic  ;!. — *^i>l'ic'illi  (j.'ciiiiini). 

This  sub-ti'ibe  is  also  represented  in  our  fauna  by  a  sinfrlc 
genus,  Seriea,  of  universal  distribution.  'I'hey  are  oblong,  emi- 
ve.\  insects,  of  a  brown  color,  usually  with  iridescent  rellection?-; 
liie  elytra  arc  indistinctly  .'-uleate;  the  pygiiliuin  is  sonietinio 
)tartly  covered  by  the  elytra. 

It  is  readib  distinguished  from  all  others  of  this  sub-family  liy 
the  lalirum  being  connate  with  the  under  surlace  of  llie  cl^ll(■u^, 
and  therel'ore  indistinct. 

The  filih  ventral  segment  and  the  ]»roi)ygidium  are  separated 
by  a  distinct  suti're,  and  the  spiracle  is  placed  e.\ternal  to  this 
suture,  half  way  between  the  anterior  and  posterior  margin  ot' 
the  ventral  segment.  The  posterior  coxie  are  flat,  and  l)ruadly 
dilated. 

SuIi-Ti-iIm'  4.— Iflucrndacts'liiii. 

Three  species  of  Macrodactylus,  distributed  from  the  Atlantic 
to  Arizona,  alone  represent  this  group  in  our  fauna;  they  arc 
eomnu)nly  known  as  rose-liugs,  and  arc  very  tlestructive  to  roses 
when  in  bloom.  'I'hey  are  elongate,  brownish  insects,  densely 
eovei'cd  with  ochreons  scales,  so  as  to  appear  udlow ;  the  tar.-i 
are  very  long;  the  claws  long,  slender,  diverging,  clert  al  tip: 
the  fifih  ventral  segment  and  propygidiuni  are  connate,  lorndng 
a  solid  ring,  and  the  last  spiracle  is  placed  on  the  suture.  The 
labrum  is  not  connate  with  the  cl^'iteus;  tin.'  nientum  is  narrow, 
and  channelli'fl;  the  anterior  co.xa-  arc  conical  and  pronnneiil : 
the  ventral  segments  are  not  conmite,  and  the  legs  are  slender. 

Siili-Ti'ilie  .'>.— $(>riroi<lini. 

This  sul)-tribe,  as  defined  by  Lacordaire,  differs  from  the  olher> 
having  conical,  prominent  anteri<ir  co.\ai,  by  the  labrum  being 
distinct,  and  the  mentnni  not  elongate  and  channelled,  as  in 
Macrodaetyli.  A  ))ortion  having  chelate  ungues  has  been  sepa- 
rated to  form  tb(!  sub-tribe  Dichelonychini. 

'I"he  ligula  is  connate  with  the  nu'titum,  which  is  concavii;  the 
labrum  is  short  and  emargimite;  the  mandibles  not  prominent;

The  genera  of  this  sub-lrilic  were  known  only  from  Africa, 
Australia,  and  Polynesia,  until  the  discovery  of  Pliobihui  Lee., 
a  Californian  genus,  allied,  apparently,  to  the  South  African 
'rri/fxiin  Er.,  the  characters  of  wliicli  are  very  iiulelinitely  made 
known  ;  but,  from  the  dilfereiiee  of  locality,  the  two  genera  can- 
not be  sujiposed  to  be  identical. 

The  only  character  by  which  this  sub-tribe  is  distinguished 
from  Ihe  jtrcceding  is  that  the  ventral  segments  are  not  connate, 
and  the  prothorax  margined  at  apex  with  mcinlirane.  The  an- 
terior eoxic  are  a  little  more  prominent,  and  the  side  pieces  of  the 
ineiathorax  are  equally  wide. 

The  generic  characters  of  I'hobetus  are:  nntennns  '.)-  or  10- 
jointed,  varying  according  to  individuals  and  not  species ;  with 
Ihe  club  of  the  male  3-jointed,  as  long  as  the  rest  of  the  antenna; 
labrnm  transverse,  concav(>,  somewhat  enmrginate;  prothorax 
margined  in  front,  and  fringed  with  membrane ;  claws  with  a  broad 
tooth  near  the  tip,  and  an  indistinct  one  near  the  Imse. 

The  species,  P.  crmKihi.",  is  robust  in  form,  nearly  seven-tenths 
of  an  inch  long,  with  the  margins  of  the  thorax  and  body,  and 
the  whole  of  the  breast,  covered  with  very  long  hair;  tiio  elytra 
are  glabrous,  nearly  smootli,  with  n  deep  sutural  stria.

i:;r()ups,  l'elidnota>,  Areodaj,  and  Uutehe;  they  may  be  tabulated 
thus,  all  of  our  s|)ecies,  except  Poli/iiKrchiiii  lirviipvn,  which  is 
allied  to  I'arastasia,  having  entire  simple  claws: —

Insensible  transitions  through  foreign  genera  connect  closelv 
this  tribe  with  the  preceding,  but  those  found  in  our  fauna  will 
not  produce  much  difficulty  in  the  mind  of  the  .student. 

The  nientum  is  usually  narrowed  and  subaeuniinate  in  front,

This  tribe,  anion}?  its  forcijjin  nienihcrs,  numbers  the  largest 
(Joieoptera  existing;  some  of  the  genera  arc  remarkable  for  the 
size  and  form  of  horns  on  the  thorax  and  lieatl  of  the  males. 

Organs  of  strididalion  are  found  in  many  geiKira;  they  consist 
of  rugose  spaces,  usually  on  the  propygidium,  Monn;ti?  e»  on  the 
inner  surface  of  the  elytra.  'I'lie  lifth  ventral  segment  and  the

But  two  genera  of  this  sub-tribe  exist  in  our  fauna;  they  have 
tlic  appearance  of  Meloloishinm,  and  are  readily  distinguisheil 
from  the  following  sub-tribes  by  the  thorax  and  head  beinij; 
entirely  destitute  of  tulterdes,  and  by  the  clypeus  being  Hat, 
parabolic,  and  linely  nmrgined;  tin-  mandibles  project  but  slightly, 
and  are  not  toothed  externally.  The  males  have  the  lifth  joint  of 
the  anterior  tarsi  much  enlarged,  and  the  club  of  the  antenna;  is 
sometimes  longer  than  in  the  f.-male.  Stridulating  organs  none; 
posterior  tibia;  not  festooned  nor  expanded  at  tip;  mentuin  trun- 
cate in  front;  antenna'  10-jointed  (!)-jointcd  only  in  certain  species 
of  Cydoeephala) ;  the  thorax  is  oidy  partially  nmrgined  at  the 
base ;  the  prosternuin  is  prominent  behind  the  coxa; ;  the  tarsi 
are  cylindrical. 

Our  two  genera  have  the  mcRo.sternun»  scarcely  visible  between 
th(!  middle  ( oxa;;  Cydoeephala  has  the  mandibles  narrow,  scarcely 
curved;  Clnilepiis  has  them  broad,  rounded  externally,  and  curved, 

Cyclocepluila  is  generally  diffused  ;  Cbalepus  has  not  yet  beea 
found  on  tne  Pacific  slope.

Sub-Trilio  2.— Oryctlni. 

Tiie  insects  of  this  sub-tribe  vary  much  in  .size  and  form,  l)Ut 
(iiive  the  following  eliarueler.s  in  eommoii: — 

Labial  palpi  iniserted  at  the  .sides  of  the  mcnluin;  nnuidil)les 
ItroMiinent,  usually  toothed  externally;  head  more  or  less  tuber- 
culate  (exeept  in  Strategus),  always  with  some  elevations,  some- 
times armed  with  a  horn;  tiiorux  usually  tubcreulate  or  horned; 
■Ulterior  feet  not  elongate  in  the  nudes;  clypeus  not  parabolie, 
liiit  rather  triangular,  redexed  with  one  or  two  small  apieal  teeth; 
iiientum  narrowed  in  front;  posterior  tibiu)  expanded  at  the  e.»- 
ireinity,  sometimes  digitate;  first  joint  of  hind  tarsi  more  or  less 
elevated  at  its  upper  extremity.  Slridulating  organs  are  fouiid 
exeept  in  Aphonns. 

The  sexual  characters  arc  usually  in  the  greater  development 
of  horns  or  tubercles  in  the  male,  rarely  (Liyi/rua  relicluH)  in 
the  thiekening  of  the  outer  elaw  of  the  anterior  tarsi. 

Two  groups  are  represented  : —

(iroui)  I.— Fentodontes. 

Moderate-sized,  robust,  convex  sjieeies,  having  the  head  slightly 
lubereulate,  or  rather,  in  our  species,  with  small  anterior  ridges 
or  teeth,  alike  in  both  sexes;  thorax  sometimes  with  a  small  acute 
tnberele  near  the  anterior  margin,  sometimes  entirely  uniform, 
convex. 

Three  genera  occur  in  our  fauna:  Ligyrus,  generally  diffused; 
Aphonus,  from  the  Atlantic  and  Central  districts. 
Front,  tiliiii!  difjitato  ; 

Stridulating  ()i'f,'aiiH  on  tlio  inner  surface  of  tlie  elytra  ;  luandildos  toothed

Aphonus.

The  last  genus  is  founded  upon  a  Mexican  species  which 
extends  into  New  Mexico.  It  greatly  resembles  in  appearance 
Aphonus  clunalin.

In  the  iiiiijority  of  {genera  the  iiiandiblcs  are  feebly  dcvchiped,

COCiEOl'TERA    OF    NORTH    AMKttlCA. 


Elytni  usually  covering  the  ubdoincn,  rarely  short;  epi- 
pleiinu  usually  distinct,  rarely  (some  Pliytuiciini)  indistinct. 

Abdomen  with  five  free  ventral  segments,  the  sixth  visi- 
ble in  many  males,  and  occasionally  in  both  sexes. 

Li'.us  variable,  usually  slender,  thighs  IVeqnently  strongly 
clubbed,  hind  coxic  transverse,  frequently  inclosv^d  exler- 
nallv  by  prolongation  of  epimera  of  metathorax.  Tarsi 
with  join's  1-8  furnished  beneath  with  brushes  of  hair, 
sonuitimes  wanting  on  the  1st  and  2d  joints  of  hind  tarsi; 
8d  joint  einarginated  or  bilobcd,  -Ith  joint  nodiforin,  small, 
connate  with  5th  joint;  claws  simple,  rarely  (Phylieciini) 
appendiculate  or  cleft,  paronychium  slender  and  distinct  in 
Prionime,  wanting  in  the  others. 

A  fjrciit  fi'inily,  containing  an  imnioiisc  number  of  spocios, 
wiiicli  livo  in  the  hirval  state  exclusively  on  the  woody  parts  of 
plants.  'I'lie  species  are  remarkable  for  lar<r<^  size,  beauty  of 
<'olf)r,  or  elejjancf  of  form,  and  iiave  been,  on  these  accounts, 
frreat  favorites  with  collectors.  Nevertheless  tiieir  classifieation. 
and  even,  tla;  deliiiition  of  tlie  family,  present  <liirieulties  which 
have  been  called  insuperable  by  every  systematist  who  lias  yet 
attempted  the  task. 

'I'he  species  are  easily  recognized,  the  chief  variations  being 
only  tiiose  of  size,  dependent  probal)ly  on  tiic  cpnuitity  of  food 
ol)tained  l)y  the  larva,  or  the  e.vcellenee  of  its  digestive  power. 
At  any  rate,  the  differences  appear  to  be  individual  and  not  in- 
dicative of  races.  The  genera  are,  on  the  other  hand,  extremely 
indistinct,  as  at  present  defined,  for  the  reason  that  the  species 
IVecpiently  differ  not  only  by  the  usual  specific  characters  of  form, 
color,  sculiiture,  etc.,  I)nt  by  structural  peculiarities  of  consider- 
able nu)nierit,  sometimes  sexual,  soinetiincs  asexual.  Hy  reganl- 
ing  these  peculiarities  as  of  generic  value,  tiic  number  of  genera 
(as  in  birds)  has  been  vastly  and  unnecessarily  increased,  and 
the  system  of  classiticaticni  correspondingly  diluted,  so  that  the 
nnu-e  es.seiitial  points  of  resemldance  l)etwecpi  allied  forms  are 
lost  sight  of,  .and  the  arrangement  becomes  (piite  artificial. 
Frecpicnt  reference  will  ite  niaile  in  the  following  pages  to  the 
misplacement  of  genera  by  the  best  authorities ;  and,  also,  what 
tends  to  greater  confusion,  to  errors  of  description  in  several 
of  our  genera,  which  lead  to  an  incorrect  appreciation  of  their 
relations.

Several  clinrnctcrs  which  have  been  recently  adopteil  for  the

one  of  the  most  indefinite,  and  we  have,  therefore,  rejected  it  as 
fur  as  possible  in  the  following  scheme.

ill  till!  Cerainliycida!  there  is  a  tendency  in  the  epimera  of  the

ill  the  Chrysoinelidic  the  1st  ventral  is  prolonged  forwanls  at  the

(inly  siiiire  tin;  developnu^nt  of  the  higher  broad-leaved  plants. 

And  in  continuation  of  this  same  subject,  we  would  rcl'er  the 
liilliciilties  of  classilicalion  of  the  Loiigicoriis  to  the  fact,  that

luodillcation,  tliroughout  long  geologieal  periods.  The  diversity 
of  speeilie  forms  seems  endless,  running  into  infinite;  vnrieties  of 
grotes(pie,  ornamented,  and  extrnonlinary  shapes;  and  nearly 
every  species  has  structural  peculiarities  for  its  specific  ehiirnc- 
ters ;  so  tlmt  in  no  family  can  genera  be  made  so  easily  and 
numerously  as  here.  Analysis  is  too  easy,  and  has  already  been 
pushed,  perhaps,  to  too  great  an  extent."

Sub-Family  I.— PRIONINyE. 

The  insects  of  this  sub-family  are  generally  of  hirge  size,  con- 
taining in  fact,  tlie  longest  Coleoptera  known;  the  color  is  brown 
or  black,  and  the  elytra  usually  coriaceous  in  ajipearance,  becom- 
ing metallic  iim!  of  lirnier  consistence  in  some  of  tiie  geiieni 
with  finely  granulated  eyes.  The  labrum  is  connate  with  tin" 
epistoma.  Tiio  ligula  is  always  entirely  <  orneous.  without  di;-- 
tinct  paragiosssB ;  the  supports  of  the  labial  \k\\\)'\  are  conmiie 
with  liie  ligula.  The  mandil)les  are  strong,  frcciucntiy  elongated 
in  the  males,  and  are  destitute  of  menibram!  or  iiiohir  tootii.  The 
lobes  of  tiie  iiiaxillic  are  small,  the  inner  one  obsolete,  and  tiie 
hist  joint  of  the  palpi  is  trinngiilar.  TIk;  antenna'  are  fiiriiishcd 
with  poriferous  spaci's,  varying  iiceording  to  the  genus  and  tribe. 
The  prothorax  is  always  distinctly  margined,  the  front  coxie  iii'e 
transverse,  with  distinct  trochantin. 

The  mesonotum  never  has  stridulating  surfaces,  such  as  are 
seen  in  most  other  Cerainhycida';  some  of  tho  species,  however, 
have  tho  epipleura;  covered  with  line  transver,se  lines,  and  a  noise

Mexico.  The  tribe  is  easily  known  liy  the  prothorax  l)eing  much 
liroiider  in  the  male  than  in  the  female,  and  finely  puiiclnred; 
ill  the  latter  se.\  the  sculpture  is  very  course,  and  the  small  leelh 
of  the  lateral  margin  longer  and  more  acute.  The  head  is  small, 
the  eyes  rcniform  and  coarsely  granulated. ;  ipitenna'  II -jointed, 
slender,  two-thirds  the  length  of  the  body  in  tin'  %,  aliout  half 
the  length  of  the  body  in  the  ?,  rough  with  elevated  punctures,

erons  .spaces  on  tin;  lUl  joint  small  iiieoiispicuoiis,  on  the  under

outer  joints  beiMiinc  I'litirely  ))iiriferous,  and  irregularly  reticulated 
with  line  elevated  lines  forming  elongate  cells,  which  are  much 
less  distinct,  ami  in  fact  hardly  to  be  seen    n  the  male. 

'!"he  generic  characters  are  not  suniciently  distinct  from  the 
JMiropean  species  K.  falwr  to  warrant  the  retention  of  the  genus 
Tricliociiemiii  proposed  in  the  earliest  description  of  this  insect. 

Trill.  II.— :tiAM>ono\Ti:vi.

Florida  is  before  us  that  is  61  mm.  long),  with  the  aides  of  the

The  ndinities  of  this  trilie  lead  from  the  last  groups  of  Ceiiun- 
byeini,  towards  the  triiies  with  finely  granulated  eyes,  Leptmini 
on  the  one  side,  and  Callidiini  (ui  the  <ither. 

(iiciiiii  I. — Obria. 

This  group  contains  a  few  small  species  in  which  the  gramilii- 
tion  of  the  eyes  lias  ceased  to  be  of  primary  importance;  Imi 
which  is  easily  distinguished  by  the  1st,  segment,  of  the  abdoMiiii 
being  very  long,  and  the  iJd  and  following  irregular,  hairy,  ex- 
cavated or  dofornu'd  in  the  9. 

The  mandibles  are  small  and  acute,  the  anlenmc  slender, 
.long  as,  or  shortei'  than,  the  body;  the  palpi  are  unecpial,  ami  iIm 
last  joint  is  rarely  dilated.  The  anlennai  arc  slender,  and  tin 
2d  joint  is  larger  than  in  genuine  Cevainbycini,  The  prothoiii.x 
is  variable  in  form,  always,  however,  constricted  and  pcdniirii 
lated  at  base,  and  mirrower  than  the  elytra;  the  front  coxa'  an 
conical,  prominent,  contiguous,  cavities  small,  roinnled  or  anun 
lated,  closed  beliintl;  middle  coxal  cavities  not  open  externally 
The  thighs  are  strongly  elavate,  the  tibial  spurs  small  or  modi' 
rate,  and  the  Isl  joint  of  the  hind  tarsi  is  as  long  as  the  lw( 
following. 

It  is  worthy  of  remark  that  in  Obrium  the  structuri!  of  the  eye< 
has  merely  Hpocilic  signilieanee ;  in  our  (>.  ruhnnn  the  eyes  iiiv 
very  coarsely  granulated,  while  in  the  nearly  allied  Kuropeaa  0. 
briiiini'um  the  lenses  are  much  smaller.

A  very  lu'culiar  tribe,  refulliiij^  Ibidion  by  its  sloiidur,  cvlia- 
drinil  Ibrin,  but.  not  related  to  it  nor  to  any  oilier  knowu  to  u.s. 

IJiit  one  speeios  Ancijloct'rn  rtKjirolHx,  black  with  searlet  elytiu 
and  abdomen,  is  found  in  our  Southern  States  from  Morth  Caro- 
lina to  Texas. 

Tribt)  Vil.— PARI!!)Ti:.tlll.\I. 

We  have  adopteil  the  iianie  of  this  triiie  from  Laeordairc;  it  has 
two  re[)resenlatives  in  our  fauna;  four  species  of  Pteroplanis 
from  Florida,  Texas,  New  Mexico,  and  Arizona,  and  lloloi)ieura, 
found  in  California. 

The  head  is  niodi'rate,  niandii)les  small,  acute,  curved  ;  the  eyes 
large,  very  deeply  emarninate,  not  very  fine'y  {rranniated,  and 
eiubraeing  the  base  of  the  antennae  rather  less  than  usual,  the 
upper  lolie  is  hirircr  than  usual;  the  front  is  i,;Hi;  r  liat,  with 
till!  transverse  suture  very  deep;  the  palpi  short,  witli  the  last 
joint  cylindrical,  truiieate  .'it  tip;  the  iiienluiii  is  trapezoidal,  ami 
more  porrect  than  in  lu'iji'hboriiiir  g'roiips,  beiii!;  almost  as  in 
Callidium;  the  antenna)  Ci?)  are  a  little  more  than  half  as  long  as 
the  body,  stout,  serrate,  and  velvety;  the  1st  joint  is  ns  huig  as 
the  ;id.  but  stouter,  the  'id  is  oiie-lhird  the  size  of  the  JJ<1,  the  4th 
shorter  than  the  5th,  which  is  the  longest,  the  following  diminish 
in  leiiglii.  The  jirothorax  is  rounded  on  the  sides,  truncate  in 
front,  bi>iiiuate  at  base;  scutelluni  variable  in  form;  elytra  a  little 
wider  from  the  base,  rounded  at  tip,  with  the  suture,  margin,  and 
three  iliseoidal  eosta^  elevated,  the  intermediate  costa  liciiig  the 
longest;  epiplenrtu  well  marked,  extending  to  the  lip.  l*ro- 
steriiiiin  narrow  between  the  co.xa',  which  are  rounded,  wilh  the 
cavities  open  behind,  and  feebly  angulaled  externally;  nieso- 
sternuni  Hat,  triangular,  co.xal  cavities  widely  open  externally; 
opiniera  of  inetathorax  moderately  wide,  |)arallel.  Ventral  .seg- 
ments nearly  ecpial.  Legs  short,  slender,  thighs  not  elavate, 
tibial  spurs  very  .small,  1st  joint  of  hind  tar.si  as  long  as  the  two 
following.  The  stridniating  plate  is  very  finely  striate,  large 
and  undivided,  with  a  row  of  pnnetures  each  side.  On  each  side 
of  the  lU'onotum  there  is  an  elliptical  depressed  space,  ttderably 
well  delined  by  an  acute  edge. 

This  like  the  following  tribe  is  n  transition  form;  the  2d  joint 
of  the  anienme  is  too  large  for  the  series  in  which  we  have  ]>lace(l

Oregon  and  A'aneonver,  a  large,  elongate,  velvety  blaek  insect, 
with  bands  and  antennal  rings  of  cinereous.  The  head  is  mode-

sericeous,  densely  pubescent,  joints  ;>-\  with  a  tuft  of  longer 
hair  at  the  ape.v,  last  joint  feebly  divided  in  % .  Mandibles  stout, 
acute,  with  a  snuili  tooth  near  the  base;  nienlum  narrowed  in 
trout,  entirely  corneous;  jialpi  nearly  eipial,  truncate  at  tip.  Pro- 
tliorax  constricted  at  base  and  ape.v,  with  an  acute  lateral  spine 
tach  side,  and  two  acute  dorsal  tubercles;  prosterniini  rather 
iiroad,  co.xal  cavities  strongly  angiilated,  widely  open  behind; 
iiicsostcrnuni  broad,  truiuate  behind,  declivous  ".i  front;  epimera 
very  large,  extending  to  the  co.xal  cavities;  nietasterniiiu  not 
acutely  einargiiuite  behind,  episterna  ratlier  wide,  narrowed 
licliind,  and  nearly  jtointed  ;  intercoxal  process  of  1st  ventral 
hroadly  rounded  in  front,  segments  lu'arly  ecpial  in  length,  oth 
tiiiiicale  at  tip,  with  an  acute,  short,  medial  cleft  in  9;  shorter, 
tiiangularly  iiui)ressed,  aiul  hairy  in  %;  tlie  last  dorsal  in  %  is 
cjccply  f  inarginate,  and  in  ?  rounded  and  subtruncate;  the  (ith 
ventral  anil  corresponding  interior  dorsal  segment  is  proinim^ut 
and  truncate  in  9.  Legs  slen<ler,  moderately  long,  thighs  not 
ilavate,  tibial  spurs  snuill,  1st  joint  "f  hind  tarsi  as  long  as  the 
two  following  united. 

The  allinities  of  this  tribe  are  somewhat  doubtful;  the  sen- 
ii'llum  is  rounded  behind;  the  niesonotum  is  smooth,  with  a  broad 
medial  vitta  of  stridulating  surface,  and  a  small  lateral  s|)ace  is 
pniicturcd  anil  pubescent.  The  form  of  the  front  eoxse  is  very

tarsi  broad,  1st  joint  of  hind  pair  scarcely  longer  than  the  2d. 

An  anomalous  group,  having  an  evident  allinity  towards  C"yi- 
lene  of  the  tribe  C'lytiiu. 

Oiiuii)  II — Tracbyderes. 

Insects  of  large  size,  and  glabrous  surface,  having  the  antemiie 
compressed,  much  longer  than  the  body  in  1,  with  vcit  distincl 
poiiferons  system,  11th  joint  either  simple  or  npi)endi(uiate;  the 
mandibles  of  Dendrobias  %  are  very  long,  and  have  an  acute 
tooth  near  the  tip,  so  as  to  appear  en)arginate,  without  really 
being  so.  The  palpi  June  the  last  joint  cylintlrical,  and  deeply 
foveate.  'I"he  seutellum  is  very  large,  acutely  triangular;  nieso- 
notum  with  narrow  stridulating  plate.  Klytra  convex,  iiairowcd 
from  the  base,  rounded  at  tip.  I'rothorax  variable  in  form,  tuber- 
culate  on  the  disk,  and  strdugly  armed  on  the  sides  in  Demlro- 
bias,  uniformly  convex  in  Li.ssonotus;  prosternum  peri)endicu- 
hirly  declivous  in  both,  armed  also  with  a  large  tubercle  in  front 
of  iheeo.xa;  in  Dendrobias;  mesosternnm  elevated,  perpendieular

eonipo.sed  of  heterogeneous  material.  However  thit*  may  prove 
on  more  extended  observation,  the  group  ats  here  defined  contains 
ill!  those  genera  in  our  fauna  in  which  the  eyes  are  finely  granu- 
iaii'il,  di^eply  emarginate,  with  the  upper  lobe  wide;  the  scuteiluin 
acute,  1ml  not  very  large,  though  sometimes  elongate;  and  the 
impthorax  not  distinctly  lohed,  but  only  feebly  bisimmte  or  trun- 
cate at  base.  The  antenuiU  are  more  slender  than  in  Trachyderes, 
and  the  poriferous  system  is  much  less  di.->tinet,  or  even  obsolete, 
tiioiigh  in  Stenaspis  it  is  still  quite  obvious,  and  the  joints  are 
ciuinate  and  bisulcate.  In  IJatyle  the  last  joint  of  the  })alpi 
( wlii('li  is  sui)eylindrieal  and  truncate)  is  very  feebly  impressed. 

'file  antenna!  tubercles  are  either  much  elevated,  leaving  a 
concavity  between  them,  or  scarcely  elevated,  in  which  case  the 
vertex  is  nearly  flat;  the  front  in  the  former  is  very  large,  sipiare, 
and  perpcMidicular,  and  the  gemu  are  long;  in  the  latter  the  tuber- 
cles are  less  eli^vated,  the  front  is  moderate,  declivous,  and  the

The  elo.sest  affinities  of  this  genus  in  the  scries  with  finely  giiiiui- 
lated  eyes  are  evidently  with  Cyllene,  l)ut  there  is  an  etpially  i\  - 
dent  cross  allliiity  in  the  direction  of  Elaphidion,  Sphierion,  v\r. 

Hiityle,  associated  with  Stenosphenus  by  Lacordaire,  lias  ilit 
seutelliini  acutely  pointed,  the  hind  legs  elongated,  the  antennul 
tubercles  more  elevated,  and  the  eyes  more  prominent.  It  sci  in.- 
to  us  a  degraded  ally  of  rurpuricenus,  and  it  has  been  jiiiui  il 
accordingly.

tral segments  diminishing  gradually  in  length. 

The  scntellum  is  obtusely  triangular  in  some  species  of  Cyl- 
kne,  rounded  in  the  other  genera;  the  mesonotum  is  punctured, 
and  hairy  at  the  sitles,  and  has  a  large  undivided,  very  linely 
striate  slriduhiting  surface. 

Till!  gi'iiera  are  numerous,  and  indicate  lliree  groups;  the 
nflinities  are  in  various  directions,  to  Megaderus,  Caliidinni,  and 
liy  a  gradual  transition  in  Kuderees,  etc.,  towards  certain  La  mi  ides.

yellow,  white,  and  black  piibesceiiee,  and  the  sculpture  is  always 
of  fine  ])unctures;  in  some  speeies  small  elevations  on  the  pro-

wings  arc  not  foUlei 


at  the  end.  In  this  connection,  it  is  important  to  observe  that 
in  Stenopternrt  and  Molorciins,  which  have  abbreviated  elytra, 
the  wings  are  not  straight,  but  folded  in  the  usual  inannei'. 

Although  the  under  surface  of  the  head  is  linuted  each  side  by 
a  line,  as  in  other  licpturoides,  tlic  line  is  less  defined  and  tiie 
nientigcrous  process  is  not  more  developed  than  in  Cerauil)y('oi(l(!s, 
and  the  ineutuin  has  the  short  transverse  form  so  frequent  in  that 
.-^'■ries,  and  totally  unlike  the  ordinary  Leptura  type. 

I'rof.  liaeordairo  describes  the  front  coxal  cavities  as  open

The  eyes  are  very  deeply  eniiiri^imite  in  Pyrutrielius.  roumli'd. 
witli  a  smiill  but  ilisiinet  eamrgiimtioii  iii  Eiieyelops,  feebly  eiiiiu'- 
{riiiate  ill  Leptalia. 

Tiie  genera  may  be  thus  distinguished: 

Tarsi  wider,  joiiit.s  l-l!  lirush-likf  bi'iioath.  Pyrotrichus. 

Tarsi  sli'iuU^r,  1st  ji)iiit  vovy  loiii,'; 

llinil  tarsi  with  liasal  joint  sukato,  bnisli-likc!  at  tlio  sides.     Leptalia. 

Hind  tarsi  with  basal  joint  cylindrical.  Encyciopa 

The  dKrercnee.s  in  the  tarsi  are  .similar  to  those  observed  in 
the  three  groups  of  Lepturini.  J'yrotriehns  being  similar  to 
Khagiiim,  Leptalia  to  the  Toxotus  group,  and  Kiu'yelops  to  the 
genuine  Leplune. 

To  Leptalia  belongs  Anoplodfra  macileiita  ^fann.,  a  black 
speeie.s  from  Alaska;  A.  Krankenlneiiseri  jlliinn.  is  a  variety  wiili 
striped  elytra  and  yellow  legs;  Leptura  f'useieollis  Lfc.  is  a 
larger  variety  from  Vaneonver  ami  Calirortiia,  in  wliieh  the  elyiia 
are  also  striped,  and  the  legs  yelhtw,  sometimes  varied  with  black. 
The  reference  to  Anoplodera  was  .-;ngiihirly  iiia|ipropriate,  since

Tribe  xviii.-  li:pti;rixi. 

The  numerous  species  composing  this  tribe  are  easily  recog- 
nized by  the  pronniieiil  conical  front  coxa',  with  the  cavities 
augnlated  externally,  open,  somelimes  almost  closed  Ijchind ; 
middle  coxal  cavities  widely  open  externally;  the  palpi  are 
always  unctpial,  the  imixillary  elongated,  the  last  joint  cylindriciil, 
(M-  triangular,  impressed.  Tiie  head  is  variabh'  in  form,  cither 
gradually  narrowed  behind  the  eyes,  or  suddenly  and  stronglv 
constrii'ted,  in  either  cas('  the  neck  is  long;  the  fnuit  is  slighilv 
declivous,  and  the  antcnmu  arc  inserted  well  in  front  of  the  eyes 
or  slightly  between  thciu  ;  the  eyes  are  oval,  longitudinal,  or 
slightly  obli(pic,  entire  or  einarginated.  Tin'  imindil)lcs  are  (hit, 
acute,  and  fringed  on  the  inner  margin.  'I'he  liyposloma  is 
defim-d  ijy  very  distinct  lateral  lines,  the  meutigeroii.s  process  i- 
very  distim;t,  iind  the  nientuni  Hat  and  trapezoidal.  The  other 
characters  are  varial)le,  tin;  anteniue  are  usually  slender,  S(nne- 
times  snbscrratc;  the  prothorax  is  usually  wider  at  base,  soiiie-

in  North  America  to  the  second  character;  the  third  ciiaracter  is 
lost  in  some  genera  of  low  organization,  sucii  as  Methia,  Dyspluig;!, 
etc.,  which  arc  only  feebly  dilferentiated  from  the  Oeme  group  ot' 


/'eraniovcinic.

luted,  rarely  (piite  coarsely  granulated;  eniargiiiuted,  freipieiiily 
divided,  sometinies  (Spalacopsis)  with  the  upper  loi)e  wanting.  ■' 
The  front,  coxie  are  rounded,  never  transverse,  the  coxal  fissure  is 
frequently  open,  so  that  tlie  cavity  becomes  angiilated,  liul  this 
character,  as  in  Ceranibyeidic,  is  not  of  great  importance;  tluy 
are  closed  behind  in  nearly  all,  widely  open  in  Methiini,  with  a 
tendency  to  become  open  in  Monohaininini.  'I"he  middle  co.va' 
are  eiilirely  closed  iiy  the  sternal  pieces  in  the  liigher  forms  of 
each  series,  ojien  to  the  side  pieces  in  the  others,  but  this  ciiaracter 


is  al 


so  oi  small  iinportanee. 


'i'lie  metasteriiiini  never  has  scent 


glands;  and  the  stridiilating  plate  of  the  iiiesonotiim  is  always 
undivided,  Ihoiigh  freipiently  narrow.  The  ventral  segments  iiic 
always  ,5,  and  present  no  remarkable  chanieters.  The  legs  are 
usually  short,  sometimes  (Moiiohammus  1,  Doreaschema)  long: 


middle  til 


with  a  tubercle  or  sinus  on  the  outer  face  in  nio>t 


genera  ;   tibial   spurs  short ;   iingiK  s  either  ilivurictitr  (exieiidiiej 
in  a  iiliine  at-  right  aiigh's  to  the  length  of  the  last  joint),  or  <// 


vcrijciil.  (not  in  the 


plane,  but   forming  an  angle).     Tli 


character,  first  oliserved  iiy  liiicordaire,  seems  to  lie  of  great 
value:  in  the  true  Ceramltycidic  the  daws  do  not  appear  to  vary

found  in  the  upper  part  of  (Jcorgia.  The  head  is  rather  large, 
tiie  front  short,  scarcely  vertical,  the  siipiiort  of  laiirnni  visible, 
coriaceous,  labrnni  snnill,  rounded  in  from.  Palpi  very  niuqnal, 
with  the  last  joint  securiform.  Antennio  slender,  as  long  as  the 
body,  scape  rather  slotit,  as  long  as  the  Jjd  joint,  rounded  at  tip, 
without  cicatrix  ;  od  joint  not  longer  than  4tli ;  eyes  small  elon- 
gate, coarsely  granulated,  lower  lobe  narrow.  I'mlluirax  as  wide 
as  the  head,  with  an  acute  lateral  spine,  rather  in  front  of  the 
middle.  l-'Jylra  elongate  not  wider  than  prothorax.  Inlercoxal 
process  of  iirst  ventral  segment  acute. 

l''ront  coxal  cavities  angnlated,  closed  behind;  middle  ones 
migulated,  closed  externally;  thighs  strongly  clavate,  IVont  tibiic 
curved  inwards  and  feebly  suleate,  nuddle  ones  absolutely  without

The  lateral  Inlurcle  of  the  thorax,  its  observed  by  Dr.  LeCoiite, 
varies  in  position  from  sni)-median  to  sub-basal. 

The  table  of  the  genera  of  this  tribe,  as  deliiied  by  Dr.  LoConto 
in  the  first  edition  of  this  work,  requires  some  nniditleatioii  by 
the  omission  of  Loidiopcenm  :  and  Stenudins,  and  the  introdiie- 
tion  of  M<'(()frtarU(.'<  (Kntessns  /vcc  ). 

The  species  jilaecd  provisioiiiiUy  in  T,opliop{riini  seems  rather  a 
I'ligDinicheriis  allied  to  /'.  orfijoniin,  but  with  the  lateral  spine  of 
(he  thorax  as  strong  as  in  /'.  (■riiiih(s. 

Slcrnidiitit  is  tlie  ecpiivalent  of  T,io])us,  and  those  species  for- 
merly tinder  the  latter  name  are  added  to  Leptiirgcs. 

Mii'ohioiiiis  Dates  (luitessus  Lrc),  is  adiled  from  the  next 
group,  in  which  it  Lad  liecii  doubtfully  placed  liy  Dr.  Let-onte, 
he  knowing  the  males  only,  while  thi'  description  by  Mr.  Hates, 
iniblislied   but  a  few  months  before,  liad  not  yet   reached  this 

Collllll'v. 

Jh'ctrii  is  also  added  to  the  group  as  its  cliaractcrs  do  not 
warrant  a  wider  separation. 
The  genera  now  known  in  our  fauna  are  as  follows; —

truncate  at  tip.  'i'lie  antenme  nvv  as  long  as  the  body,  or  a  little 
sliortcr;  the  scape  is  m-ariy  cylindrical,  a  little  shorter  than  the 
3il  Joint,  without  ai)icai  cicatrix;  the  outer  joints  scarcely  diminish 
in  length.  The  protliorax  is  cylindrical,  entirely  umirined,  and 
without  tubercles;  the  elytra  are  wider  than  the  protliorax, 
cylindrical,  u.-^ually  rounded  at  tip,  rarely  {laliarutu)  the  suture 
is  armed  with  a  spine,  or  {ohliijiia)  tin;  tip  is  attenuated  and  acu- 
minate. 

The  front  eoXiP  are  angnhited  externally  with  distinct  trochant in, 
and  closed  liehiiiil;  ihe  middle  coxal  cavities  are  angnhited,  iii)en 
externally,  with  disiiiict  trocliantin.  The  prosti'rnnm  is  very 
iini'i'ovv  between  tin  coxa;,  and  the  mesosternni.i  acute  behind.

rullier  sliiM''.  in  general,  claws  divaricate;  the  inner  one  of  the 
IViint  and  middle  ])air  in  the  %  of  most  of  our  species  armed  with 
a  nmnded  lobe  or  tooth,  which  is  wanting  in  S.  moeala,  and  con- 
Coliii;  iiiid  in  the  Ktiropean  species. 

The  genus  Saperda  alone  is  represented  in  our  fauna.  Thus 
far,  none  iiav(>  been  found  on  the  I'aeilie  slojjc,  except  .S.  moc.tla, 
11  nortiiern  species,  which  extends  from  Canada  to  Oregon. 

Some  of  the  species  are  very  destructive  to  cnltivnted  trees, 
'"'ring  into  the  wood,  or  destroying  the  subcortical  tissues  of  ilie 
roots.

Styloxus  is  founded  on  a  species  from  Lower  California,  sunio- 
what  larger  than  Methia  pusilla,  but  also  of  a  uniform  biowii 
color.     Idcemea  is  established  on  a  much  larger  Texan  species.

Metastcrnum  either  long  or  short  side  pieces. 

Klytra  usually  covering  the  dorsal  segments,  sometimes 
leaving  the  pygidium  exposed  (Camptosomes);  rarelv  (in 
some  genera  of  Gallerucini)  smaller,  and  not  covering  the 
greatly  cidargcd  female  abdomen;  epipleurui  usually  dis- 
tinct. 

Abdomen  with  five  ventral  segments,  varying  in  pro- 
portion. 

Anterior  coxai  varying  in  form  and  position ;  miildle  coxio 
either  contiguous  or  separate;  hind  coxaj  transverse,  con- 
tiguous, or  separated,  not  laminate. 

Legs  usually  short,  hind  thighs  frequently  enlarged,  and 
in  some  groups  of  Gallerucini  saltatorial;  tibiie  never  serrate, 
usiudly  without  spurs;  tarsi  with  the  joints  l-o  usually 
hroad,  covere<l  beneath  with  a  brush  ol'  hair;  3d  frecpiently 
bilobed;  4th  anchylosed  closely  to  the  oth,  which  has  two 
e(pial  claws  of  variable  form.  Rarely  (ILemonia,  and  Ste- 
iiopodius)  the  tarsi  arc  n;irivw,  and  the  last  joint  is  very  long, 
with  large  simi)le  claws,  suited  to  grasp  subaquatic  plants 
on  which  they  li"e. 

Tills  family  is  nn  immense  complex,  developed  to  llie  largest 
cxt(  lit  in  tiie  tropics,  tlioiiftli  by  no  means  wiilioiil  a  rispi'etable 
i'e|)res<'ntation  in  temperate  and  boreal  regions.  As  tlie  faiiction 
of  the  Ceramhyeidaj  is  to  hold  the  vegetable  world  in  eiieek  by 
destroying  woody  fibre,  the  IJrueliidie  ell'ect  a  similar  result  by 
attacking  the  seeds,  and  the  Clirysomeiida3  b)^  destroying  tiic 
leaver..  As  the  cellular  and  siieenleiit  leaved  plants  have  sne- 
ct'cdod  tlie  drier  and  more  iigneons  forms  of  early  geolngicai  time, 
so  have  the  C'iirys(jineli(he  jiroliably  attained  their  higliest  devel- 
opi'ient  in  the  more  recent  periods,  and  it  is  therefore  interesting 
to  note  that  their  relations  witli  lviiyneho|)liora  are  pro])ortion- 
ntdy  more  feeble  than  those  of  the  otiier  two  families  above  men- 
tinned. 

Among  the  species  of  this  family  are  to  be  found  some  of  the 
most  formidable  Coleopterous  pests  of  Agriculture;  but  with  few 
cxeeptions  tiiey  belong  to  the  triiie  Oallerueini.  A  notable  ex- 
ception, however,  is  the  Dorijphora  decemlineata,  the  world- 
known  Colorado  potato-bug. 

In  order  to  make  the  tables  of  frii)es  and  genera  more  intelli- 
pilile  to  the  stu<h'nt,  it  will  be  jjroper  to  define  the  diifereiit  forms 
i)f  tarsal  claws,  which  have  been  used  in  the  classilication  of  this 
very  troublesome  family.

Tiilic  IV.— CLYTIinilVI. 

This  tribe  consists  of  species  of  compact,  stout,  pulieylindrical 
form,  having  the  ju'othora.v  margined  at  the  .sides,  liltetl  ciosoiy 
to  till!  elytra;  the  front  co.\ii;  are  transverse,  more  oi*  less  promi- 
nent, ami  have  a  large  trochanlin.  They  are  sometimes  contigu- 
ous, .sometimes  sepiu'aled  by  tlie  prosternum,  but  the  ervities  are 
(•lii>ed  behind.  The  1st  ventral  segment  is  longer  limn  tlii;  :i<l; 
ihu  4111  and  oth  are  shorter  at  tlie  middle  and  connate,  so  thai 
the  [lygidiuni  becomes  sligliliy  iii(le.\ed.  The  elytra  are  loiied  at 
the  sides,  the  cpipleura;  arc  apjiiircnt  only  near  the  base,  and  tlie 
liygidiam  i.s  exposed.  The  head  is  large  and  delicved;  the  eyes 
lire  transverse,  and  sonieliines^omarginate  in  frmit;  the  antenna? 
lire  widely  separated,  .short,  serrate,  and  ll-Jdinted;  the  matidi- 
hles  are  sonietinu's  much  larger  in  the  male,  and  tlie  front  legs 
lire  occasionally  elongated  in  the  same  se.\.  'I'he  legs  are  siiorl 
luid  stout,  (he  tarsi  broad,  the  claws  simph-  or  appendiculale. 
The  aiileiimu  are  not  received  in  grooves  in  our  genera.

Dr.  Cliapuis  states  (Oi'n.  Col.  LiiconlaiiT,  .\.  :]""))  tliat  tlio  iM 
tarsal  joint,  in  Liiia,  is  broad  and  L-ntire,  ijut  wo  lind  it  di'opiv 
liilolit'd  in  all  of  our  spcjius,  including  L.  trcniu'u,  wliii'li  is 
coninn)n  to  Ixith  continents. 

Tlicre  lias  been  an  ohjcction,  wliieii  we  think  is  ill  fonndcil,  an 
the  part  ol' several  l^urojiean  sysleniatists,  to  reeeiving  liie  Moiili 
Anieriean  speeies,  placed  by  Mr.  \V.  V.  Rogers  (I'roe.  Acad.  Mat. 
Sei.,  iSod,  ;i(t),  in  JJufi/plmru.  The  speeies  of  Jhtri/jiliord  iiic 
eiiinnionly  ciniceived  to  be  tropical  '"'isects,  in  which  the  nicsd- 
sierni'in  is  more  or  less  produced  forwards.  Thi.-<  character,  a.- 
we  know  in  Aniutuihi  of  ti.o  Searabseidie,  has  small  sij-nilieance, 
and  we  would  liierelbre  |)refer,  in  onr  desire  to  avoid  unnecessaiy 
n\Mlliplicalion  of  genera,  to  regard  in  this  family  and  trilie,  ihr 
palpi  as  of  more  <  .Misetinence  than  the  niesoslernnni  tor  the  deli- 
nition  of  genera.  We  do  this  with  the  less  relnciance,  becan.-c 
we  do  not  observe  in  our  si)ccies  any  particular  transition  between 
tiie  two  sets  of  forms  to  wliieii  we  ascribe  the  generic  names  above 
given. 

'I'he  species  of  C/iri/ftomela  may  be  divided  into  sub-genera  an

acutely  toothed  on  the  outer  margin.  'I'he  1st  and  .'id  joints  nf 
the  tarsi  are  broad  and  spongy;  the  2il  joint  is  snudler  and  less

Tills  group  is  separated  i'roin  the  piTccdiiig  by  the  front  tlliiai 
'  being  slender,  neither  toothed  nor  produei'd  at  tip,  and  by  the 
tiir.si  having  the  .'Jd  joini  iiiueh  wider  and  larger  than  the  isl  ami 
•_M,  and  deeply  liiioiied. 

IJutone  speeies,  I'htjlloiJrctn  vuhjalixxima,  represents  the  group 
ill  our  fauna,  and  althougli  widely  dill'nscd  in  the  Atlantic  region, 
may  perhaps  have  been  iulrodueed  in  eoiniuerce. 

TiiiH'  IX.— 4;ALi:iti^c.'i:vE. 

Tiie  species  of  this  tribe  are  very  nuiuerons,  and  soiiietlnies 
ill  eonseipieiicc  of  great  variation  of  color  and  sculpture,  tjuite 
(iillieull  to  deliiie.  They  are  one  of  the  most  jtowerl'nl  agents  of 
('(jleopterous  type  for  the  repression  of  rt'dundant  vegetation, 
especially  in  the  tropics,  where  tlii'y  ae(iuire  a  splendor  unknown 
ill  the  temperate  zones. 

The  trilie  is  well  deliiied  by  the  insertion  of  the  auteiiiuv,  which 
in  our  genera  are  placed  upon  the  front,  let  ween  the  eyes;  they 
are  usually  approxiiuate,  and  the  front  is  generally  carinale,  with 
I  narrow  ridge.  The  eyes  are  not  eiuarginate  and  linely  granu- 
lated. Head  exposi'd,  and  itrotli(ua.\  truncate  or  eiiiar,i.',iiiate  in 
fro'it,  with  the  sides  distinctly  inargined.  Seiitel  always  visible. 
I'llytra  are  rarely  shorter  (.Metacyeia)  than  the  abdi.'.neii.  I'm- 
sternuiu  nari'ow  or  invisible  between  the  coxiu,  wlii'  ii  are  pronii- 
iieiit  and  conical,  and  have  tlii^  cavitie.^  sometimes  open,  some- 
times closed,  always  transversely  oval.  Legs  variable,  tarsal 
claws  variable,  rarely  simple.

Tlic  species  of  this  sub-fimiily  are  ilislinj^iiisiied  by  the  miihllr 
eoxie  l)eiiijr  entirely  ineiosed  hy  the  sleriia,  witiioiil  any  troehaiitin  ; 
the  side  pieees  of  tiie  iiiesotliorax  eoiisequeiitly  do  not  extend  in 
the  eoxal  cavities;  the  ventral  seynieiits  are  entirely  corneons.  the 
.'Jd  and  4tii  luiving  no  vesti^'e  of  a  posterior  coriaceous  nnnyin. 
JJesides  these  two  distinji-ni.sliing  characiers,  eoninion  to  all  ilic 
triljes,  there  aro  others  worthy  of  notice,  wldeli  belong  to  indi- 
vidual tribes,  and  are  not  found  to  recur  in  the  other  two  suli- 
fauiilies. 

The  species,  with  the  exception  of  Kpitrapini  and  a  few  'rhiiin. 
liatini,  are  aplemus,  and  the  nielasternuni  is  very  short,  exeeiii 
in  the  winged  sjiecies.  In  Zopherini  the  eyes  are  very  linelv 
granulated,  a  singular  exception  in  this  family.  The  nientum  i- 
IVe(|uently  very  large,  so  as  to  hll  entirely  the  gular  eaviiy,  and 
to  cover  completely  the  maxilhe  and  ligula,  so  that  the  gular  pm- 
cess  usually  suppiu'ting  it  ceases  to  exist.  This  character  recur- 
again  only  in  certain  Asidini  of  the  next  sid)-fandly.  The  tm-i 
are  sonietinies  sjiinous,  soiuet lines  pubesceul  beneath.  The  Inmi 
is  frequently  trilobed.

Tlicse  goiu'i'a  occur  in  Califoriiiii  aiitl  Arizoiia.  Tlie  males  of 
("ratidus  liavo  a  disiiiict  toolli  on  lliu  inner  side  of  llie  posterinr

Tile  species  of  tliese  fi-enera  are  usually  found  walivin!?  on  tiic 
surface  of  tiie  .urround  ;  but  Ampli idora  littoriilix  lives  in  colonies 
under  oak  bark. 

Tribe  IV.— TE\EBUIO:Vll\I. 

Body  moderately  elongated,  apterous,  or  winged ;  head  pro- 
longed, but  scarcely  narrowed  behind,  not  received  in  the  iIkmm.x 
as  far  as  the  'ves,  which  are  transverse  and  eniarginate,  inode- 
ratelv"  linely  granulated;  front  dilated  on  the  sides,  covering  the 
base  of  the  mandil)les;  epislonni  truncate  or  sliglilly  euiarginiile. 
Tiot  separated  from  the  labruni  by  a  <'lypeus;  antenna"  1  l-jointed, 
gradiniily  thickened  externally ;  nieniuni  small,  jiartly  concealing 
the  ligida,  inserted  upon  a  giilar  iiciluncle;  elytra  embracing 
'cebly  the  flanks  of  the  aiidonien;  epipleurie  narrow.  Anterinr 
(roxa^  gloi)os(! ;  middle  coxa'  with  distinct  trochantin;  legs  long; 
tibial  spurs  small;  tarsi  idolhed  beneath  with  silky,  golden  jiulic- 
<'ence,  oj- with  ordinary  coajse  puliescenee.  lliiid  nuirgin  of  third 
and  fonrlh  ventral  segments  subcoriaceous. 

This  tribe  (;nd)races  the  ('(elonietopides  of  Tiacordaire,  with  ii 
portion  of  liis  Tenebrionides;  the  vesliture  of  the  tarsi  appears 
to  l)e  of  more  siruclural  iniporlaMce  than  the  length  of  the  imia- 
sicrnuin,  liy  which  merely  apterous  and  winged  species  are  (li>- 
tinguished.  The  allinity  pointed  out  between  sonn-  of  the  genei'a 
and  the  trii>e  Scaurini  is  very  strong,  and  I'olypleuru.s  might  lie 
e(|ually  rtell  placed  in  the  pret'cding  tribe. 

The  gem'a  may  lie  divided  into  two  groups: — 

T.irsi  silky  pulMsci'iit  ln'iiratli.  I'rrs. 

Tarsi  cciarsi'ly  inilicscrnt  lii.'iicatii.  Tn.vKmuoM.s. 

(ir(m|)  I. — Upes. 

In  this  group  the  hind  coxa'  vary  in  position;  the  metnstcrnuni 
in  the  apterous  species  is  very  short,  iiut  in  the  winged  ones  long: 
the  epipleurai  do  not  reach  the  tip  of  the  elytra  in  nmst  of  the 
genera,  aiul  in  otinn's  they  are  gradually  narrowed,  reaching  the 
tip. 

The  spreips  are  found  uiuler  bark  of  dead  trees.  Our  genera 
are  as  followa; —

vny  small. 

Tills  tribe  consists  of  the  genus  Cononotus,  of  wliicli  three 
^liceies  are  fduiid  under  .stones  in  California;  they  are  shsuder, 
|i;de  brown,  linely  pu'iest-ent  insects  of  small  size,  having  the 
tlior.'ix  elongated,  and  regularly  conical  in  form,  and  n>iich  Jiar- 
I'dwcd  iieliind  ;  the  lateral  suture  is  nearly  elbieed,  t'lougli  still 
cnpable  of  being  Iriiced  ;  the  maxillary  palpi  are  very  long,  and 
!lii'  last  jninl  is  large  and  triangular. 

It  is  very  dilllcuh  to  indicate  the  allinities  of  this  genus;  it 
seems  to  lie  ecpndly  out  of  place  in  any  family.  It  was  formerly 
iiiiisidered  as  allied  to  Apocrypha,  of  the  'I'dielirioinda!,  a  view 
;iilopted  liy  Laeordaire  ;  iiut  the  open  antcri(jr  coxal  cavities 
tirbid  such  an  a.ssoeiation.  The  (irst  and  second  ventral  segments 
iippear  to  be  cunmite;  should  dissection  confirm  this  oi)servatioii, 
i!  will  jmint  very  strongly  towards  the  reception  of  the  genii.s  as 
11  separate  family.

with  the  elytral  margin,  the  nietasterna!  side  pieces  rarely  of  more

funbria'  become  more  evident.  In  the  former  tribe  there  are  no 
evidences  whatever  of  either  ocular  lobes  or  (imbriiu.  In  oik! 
genus,  the  prosteriium  is  more  emargiimt(^  than  usual,  giving  an 
appearance  of  slight  ocular  hjbes,  i)ul  ini  traces  whatever  ol'timbria! 
are  seen.  In  some'  of  the  genera  of  (>/iliri/(ixliii!,  the  metasternal 
Mih  pieces  become  of  moderate  width,  showing  somewhat  of  an 
approximation  to  the  genera  of  the  second  division.  Tin;  sid(i

of  Uphryastcs.

only  species  known  to  us. 

Oroui)  HI.— Strangaliodea. 

The  group,  as  cjinprised  in  the  following  table,  i.s  not  precisely 
that  intended  by  Lacordaire.  There  are  without  douljt  several 
genera  which  should  be  placed  in  his  L'reinnidctf,  l)nt  with  the 
exception  of  IMiy.xelis  we  can  tind  no  genus  presenting  such 
marked  ilill'erenees  in  the  form  of  the  scrobes  as  to  render  it 
possible  to  draw  the  line  with  any  degree  of  accuracy  between 
those  genefu  in  which  the  scrobi^s  are  strictly  lateral  and  iho-se 
with  the  scrol)es  arcuate  and  directed  inferiorly. 

The  arrangement  of  the  genera  in  the  following  table  exhibits 
a  gradual  transition  in  the  form  and  length  of  the  rostrum,  from 
Dielio.xenns  which  approaches  I'lost  nearly  Ophryastes  in  this 
respect  as  well  as  in  the  structure  <if  the  scrobes  and  alidomeii, 
to  Phyim\tinus  with  a  long  rostrum  almost  entirely  lateral  serolies 
and  normal  abd'nnen.  Cimbocera  by  its  narrower  tarsi  and  the 
strnctnre  oi"  >.ie  antenna'  approaclu's  Oidiryastcs  in  another  tlirec- 
tion.     Mt'laniv  mi)hus  reseniiiles  Ainomphus  in  form. 

The  following  tal)le  is  the  result  of  a  study  in  which  the  serial 
arrangement  e.xhiliits — 

/V/",s/,  a  gradual  iransi'ion  in  the  form  of  the  rostrum,  from  the 
more  robust  to  (he  elongate. 

Si'foiHl,  the  tendency  of  the  scrnl)cs  to  change  from  the  strongly 
lU'cuaie  to  tlie  nearly  straight,  and  shallow  form. 

Third,  the  strnettire  of  the  abdomen,  with  the  three  iiiterme- 
iliiili*  segments  nearly  e(|ual  (as  in  Ophryastes)  to  those  with 
the  abdomen  of  normal  strm'ture.

Tiie  validity  of  the  separation  of  this  as  a  distinct  group  in 
iiiir  fauna  seems  somewhat  doubtful,  the  only  eharaeter  by  means 
of  which  it  nisiy  be  distinguished  from  the  preceding  group  is 
found  in  the  position  of  the  scrobes.  We  have  adopted  a  group 
iiiiiiie  in  accordance  with  the  only  genus  known  to  us,  as  experi- 
ence has  alreaily  shown  that  groups  of  genera  formed  on  the 
'laeordaireiin  basis  are  not  ut  all  limes  e(piivalent  to  tliose 
iidoptetl  in  the  |)resent  memoir  which  is  but  a  modilicalion  and 
imiplilication  of  the  .system  suggested  by  l)r.  LeConte.

The  Poritcli  should  follow  the  Otioi'iiynclii  ffom  their  fi'rentiT 
.^iniilarily  of  form  and  stvietiire,  the  only  difference  between  ihc 
two  groups  is  found  in  the  form  of  the  claws.

Antenna;  moderate,  scape  longer  than  the  funicle  and  chili, 
moderately  arcuate;  funicle  d-joiiited;  club  brotully  oval  slightly 
flattened,  composed  in  great  part  of  the  first  joint  only,  the  oilier 
joints  retracted  and  very  indistinct.  Tarsi  long,  slender,  tiiini

prolonged;  iiiiterior  and  ndddle  tibiie  witli  inner  angle  mucroiiiile. 

The  id)ove  characters  appear  to  warrant  tiie  separation  of 
Agraplius  as  a  groni»  by  itself,  as  suggested  by  liaccu'daire,  who, 
however,  failed  to  not  ice  the  structure  of  the  anteiinal  club  ;niil

more  so  in  fact  than  in  any  other  genus  in  our  fauna.

The  species  of  this  siili-raiiiily  may  he  recognized  hy  the  nian- 
dihles  being  rarely  eiiiargiiiale  at  tip,  lull  cither  bi-eniarginatc 
with  three  apical  <'iis|is.  or  ob|i(nie,  with  three  cusps  on  the  inner 
side,  which  soinetinies  become  ell'aced  or  obsolete.  Jii  the  lir.-i 
tribes  the  inferior  cusp  is  also  .-iiaiilcr,  and  less  prominent,  but  it 
sjieedily  becomes  more  developed,  and  it  is  liy  the  final  dominance 
of  that  cii-p.  with  the  edge  of  the  mandible  which  correspond.- 
to  it,  that  the  oblicjiie  form  with  the  teeth  on  the  inner  edge,  is 
nssirned;  and  a  still  greater  iiroinineiice  of  this  inferior  edge  and 
cusp  re.-nlls  ill  liie  olili(pie  or  (lalleiied  fiiriii  of  nmndible  seen  i

are  still  more  dejircssed,  and  the  condyle  instead  of  being  on  the 
outer  side  comes  to  the  upper  siirfiicc,  po  that  the  movemunt  is

rior cusp  becomes  very  small  or  obsolete,  so  that  tlu^  mandil)les

peculiar  characters  which  distinguish  each  of  them.  The  beak

groups,  as  will  be  seen  below,  but  they  agree  in  the  ibllowing 
fliaraeter.< : — 

Mandibles  with  three  teeth.  so]iiirated  by  two  eniareinations, 
the  miildle  loolh  more  proiiiiiieni ;  in  the  group  Desmorliiues  the 
outer  side  of  tin;  inandibles,  by  the  transposition  of  thi'  apical 
tooth,  beeoiiies  toothed  as  in  Khynehiiida';  gular  peduncle  longer 
than  wide,  slightly  eniaiginale,  nicninni  small,  nol  transverse, 
ligiila  and  palpi  promiiieMt.  smaller  than  in  Ilylobiini.  The  beak 
is  eylimlrieal,  sometimes  very  long  and  >len(ler,  sonu'tinu's  rather 
stout:  the  anteniial  grooves  ecimmenee  at  a  distance  Ironi  the  tip, 
descend  obli(piely.  and  soinetimes  become  eonlluent  bi'hind.  The 
anteiMue  are  geniculate,  the  scnpe  huig  and  slender;  fnnieiilus 
usually  7-,ioiiited,  sometimes  (i'lndalns)  (i-jointed;  club  oval,  aii- 
liulated,  entirely  clothed  with  seiisifive  surl'aee  I'xccpl  in  liisso- 
rhoptrus.  I'rotliorax  with  or  without  postocular  lobes;  front  co.xie 
C()nligU(Uis,  pr(islernum  Hat,  emarginale,  or  not,  in  front;  some- 
times  (l>a,irous)  broadly  siilcaie  for  reception  of  the  beak.  .Meso- 
sternum  with  the  side  pieces  diagimally  divided,  cpinieia  not 
attaining  widely  the  liase  of  the  prothorax.  Metask'rnum  usually 
long,  rarely  (IMiyeoctetes)  vi'i'v  sIkuM  ;  side  pieces  narrow,  dilated 
ill  front.  Hind  eoxa'  wiihdy  separated,  transverse,  narrower  ex- 
tt'rnally,  and  extending  almost  to  llieelytral  margin.  Legs  never 
very  stiuit,  thighs  usually  simple,  rarely  (I»oryt(mius)  toothed; 
tibiae  truneato  at  tip  and  feebly  miiennuite  in  mo^t  genei'a,  strongly 
unguiciiiato  in  jJagoi.  Tai'si  usually  dilated,  narrow  in  eertaiii 
genera;  last  joint  someiimes  long,  sometinii's  short;  claws  not

and  coarsely  granulated ;  fuidcidus  7-joiiiletl,  lirst  joint  longer  and 
stouter,  remaining' joints  short,  closely  united;  cluh  oval,  pointed, 
entirely  pubescent,  anmilated.  rrolhorax  ()i)li(inely'  truncate  in

Tlie  genus  Urachypns  is  placed  by  liacordairo  in  his  group 
Hrirliinides  ;  it  dillers  from  the  otlier  genera  of  that  division  by 
the  narrow  linear  form.  Though  the  three  species  described

Schouherr  and  lincordaire,  we  think  tliat  they  accord  sulliciently 
to  indicate  tlie  proiiriely  of  associating  them  logctlier  a.s  a  special 
group.

tlie  fourth  segment,  and  the  siih's  of  liie  third  segnu'ut  are  thus 
cnlireiy  covered.  The  pygidiiini  is  nsmdiy  exposed  l)y  the  tips 
of  tlie  elytra  lieing  separalidy  rounded,  liut  in  Tycliius  they  arr

ventral  segments  are  less  une(iual  than  in  Krirhinini. 

'I'lie  other  characters  are  tho.ve  ciuunion  to  the  jjrcceding  lril)es: 
Itcak  long  and  usually  slender;  antenna'  inserted  far  from  the 
tip;  antenna]  grooves  directed  soniclinies  against  the  eyes,  sonie- 
tinies  helow  them.  The  eyes  are  rounded  or  nearly  so,  not  finely 
granulated.  'I'lie  fnniele  of  the  antenna'  is  (i-  or  "-jointed,  and 
the  cinl)  entirely  puljcscent  and  annulaled.  The  prothorax  has 
no  postocular  lolies;  the  prosternuin  is  .--horl,  not  strongly  eniar- 
ginalc  in  front,  and  the  eo.xa;  are  contiguous.  Tiie  side  pieces  nf

The  clyirii  arc  .-carceiy  wider  liian  the  jirotiiorax,  parallel  on  the

simple  in  the  foreign  genera. 

While  1"  .ing  a  slight  I'elation  with  the  Alagdalini  and  .\iitlio- 
noniiiii  this  tribe  adds  to  the  characters  il  has  in  common  with

long  in  front  of  the  coxie.  'I'lie  sjiace  lietwcen  the  front  eoxic  is 
almost  impereeptibie  in  our  two  species,  but  as  the  descriptions 
of  the  foreign  genera  iiieniiiui  them  as  moderately  distant,  we  infer 
that  that  cliaracter,  as  well  as  the  form  of  the  claws,  must  be 
regarded  of  small  value  in  this  tribe. 

Three  species  of  Notolonius,  two  on  Chaimvrops  palmetto  and

In  this  group  the  pectoral  groove  is  connned  to  the  prosternmn. 
and  is  not  closed  behind;  the  nu'sosternuni  is  sometimes  flat, some- 
times suddenly  declivous,  'i'lie  eyes  are  eoai'sely  granulated, 
]tartly  covered  in  repose  by  tin;  protlioraeic  lobes,  which  are 
sometiines  very  well  developed,  but  in  other  genera  arc  broad 
ami  not  pnniiinent. 

The  prolhora.x  is,  in  most  species,  comparatively  snniller  than 
in  the  other  groups,  and  usually  very  coarsely  scniptnred.  'i'lie 
elytra  are  wider  than  the  prothora.x,  with  prominent  humeri,  the 
oilier  stria  is  usually  abbreviated,  and  there  is  a  tendeiiey  to  an 
e|)ipl('iiral  fold.  'I'he  thighs  are  toothed  in  oiir  genera;  the  tibiu^ 
slender,  iiooked  at  the  ti|);  tho  claws  usniilly  toothed,  tlmiigli 
sometimes  simple  oi'  even  <'onnale  at  the  base.

a  deep  iirosternal  canal,  which  in  some  species  does  nut  extend 
upon  the  mesostcrnnni,  so  that  the  end  of  the  beak  is  free,  as  in 
Conotraehelus ;  even  when,  as  in  others,  the  inesusternuin  is  ex- 
cavated, the  Lunal  is  open  ami  not  sharply  limited  behind.  Legs

jiresorve  the  species. 

Tiio  habits,  therefore,  of  these  insects,  as  well  as  tlusir  peculi- 
arities of  structure,  deserve  a  clo;  cr  attention  than  has  yet  bei'u 
given  to  them. 

The  .snioolli  eyes,  tlie  reticulations  of  wiiieh  arc  seen  only

didic,  such  as  ndglit  perhaps  exist  ann)ng  objects  of  (piite  din'ereiit 
nature  <M'iginating  in  the  same  period  of  time.  Tliu  geographicsil 
distribution  of  the  Jirciithichu  is  also  favorable  to  tlio  Idea  that 
lliey  rei)reseiit  a  tolerably  ancient  form  of  life. 

The  great  extension  of  the  longitudinal  axis  of  the  body  exceeds 
III  s(uiie  nu-miicrs  of  this  faniily  any  proportion  that  Occurs  in 
other  C'nieoptera;  and  it  is  singular  to  see  that  a  character,  which 
usually  indicates  feebleness  <if  development,  is  here  associated  with 
densely  cliitinized  integuments,  and  great  eomiilication  of  domestic 

life. 

'IMie  faiidly  divides  itself  naturalh'  into  two  sub-families,  the 
characters  of  which  have  been  sulliciently  exposed  above.

China,  India,  and  Madagascar.  It  has  probably  been  introduced 
from  Asia.

We  a.«sociate  as  a  distinct  tribe  certain  otiier  genera,  which 
have  not  the  body  covered  with  a  crust,  but  shining  ami  liarc; 
some  of  tlie  foreign  genera  are  intu'e  or  less  setose,  liut  ours  are 
glidirous,  with  the  e.Mcptinn  of  llimalium. 

'I'lie  beak  is  never  very  short,  and  is  fre(|Uently  dilated  at  tip; 
the  antenna'  are  inserted  near  the  tip  cu'  at  the  middle;  the 
antcnini'  grooves  fre(pu'ntly  descend  r.'ipidly  on  the  sides  of  the 
beak,  an<l  soinetinn.'s  are  directed  towards  the  eyes,  but  the 
fiuienuie  are  not  received  in  repose  in  a  deep  transverse  gidar 
groove  as  in  the  next  tribe.  'I'he  club  varies  in  form,  and  in  our 
genera  thefiinirlc  is  T-jninted;  wjiclher  any  of  the  genera  of  (it her

Tribe  III.— RIIYXC'OIJXI. 

The  genera  of  this  trihe  wiiile  dilfering  Voni  those  of  the  Cos- 
soiiini  only  iiy  having  the  prosteriiuiii  ve/y  narrow  helweeii  the

approximation  to  the  Seolytiihe;  thus  I  hi' iinuilier  of  joiiiis  in  the 
fiiniele  of  the  aiileiiiiie  varies  so  as  (o  lie  barely  of  generie  value; 
the  lieak  heeonies  xei'v  iiuieli  shoi'leiied.  and  the  lieail  compara- 
tively larger,  as  in  Steiioseelis;  the  ronn  of  the  clnl)  varies,  he- 
eoiiiing  wedge-shaped,  trnnenle,  and  spmigy  at  lip  in  Wollaslouia, 
thus  r\'alling  the  form  seen  in  Uhyiieliophonis,  I'tc. ;  (piite  rounded 
or  p(-rliaps  a  little  transverse  in  Sienoseelis.  The  I'nnii  is  also 
that  of  eertain  Seolylid;e.  Uhyneolus  resendiles  closely  one  sei'- 
tion  of  llylasles,  while  Steiioseelis  has  allogeilier  the  appe;ii'anee 
of  llyliirgops  ( //.  riKii/ii'iniiK,  ('\r.). 

As  in  the  Khynehoiihora,  from  tin,'  nearly  perfect  representation 
of  jiast  and  present  forms,  there  are  almost  always  intermediate 
g"iii'ra.  to  li(\  found,  so  in  I  he  present  trihe  IMiUeopluigus  seeui-; 
to  he  one  of  such  intermediates,  and  would  he  in  place  in  the  pre- 
ceding trihe,  did  we  not  regard  the  approximate  front  eoxie  as 
having  greater  systematic  value  than  the  longer  heak  and  the 
weaker  gular  groove. 

The  untennul  grooves  always  comnience  near  the  tip  of  tlic 
heak  ami  derjcend  ohliipiely  heluw  il'e  eyes.

beyond  the  iirolonged  angles  of  the  second  joint.  The  beak  is
